New arrivals at World Museum

Here’s Paul Tyson, our Team Leader at the Aquarium, to tell us about some new arrivals at World Museum

Two large blue fish with teeth showing

I’m very pleased that we now have four Atlantic wolf fish, who have come to the World Museum aquarium from the MacDuff Aquarium in Scotland.
The Atlantic wolf fish (Anarhichas lupus), also known as the sea wolf, is a marine fish, the largest of the wolf fish family. It has been known to grow to nearly five feet in length. 

I have been keen to bring wolf fish to the aquarium since I started in November. They are extraordinary-looking creatures and I have a bit of a soft spot for them as I have worked with them for 15 years! Feeding time for the wolf fish is fun as these aggressive animals have some serious teeth. However, despite their fearsome appearance Atlantic wolf fish are only a threat to humans when defending themselves out of the water. They also produce a natural antifreeze to keep their blood moving in their cold ocean habitat.

Numbers are declining rapidly due to overfishing and by-catch, making it a Species of Concern for US authorities, and numbers in our own waters are unknown. The health of the wolf fish population is an important indicator for other sea bottom dweller species, such as cod.

If you’ve never seen them before you should come and visit us at the aquarium and take a look!
